'69 M20F Air Filter?


Recommended Posts

UPDATE:  This is, in fact, a K&N Filter.  I spoke to them today, and they said it is a special product made exclusively for Challenger Aviation, and they cannot sell it directly.  They gave me the number of (937) 387-6500 to contact them about purchasing a filter directly, with the same part number - SP-2979.

Hopefully this helps others in the future, I'll update if I am able to purchase directly from Challenger.  Otherwise, looks like I'm in for $250 for a whole replacement.  This one was neglected by the prior owner and not cleaned or oiled, and now is basically letting unfiltered air straight through.

This is the air filter on my '68 M20F.  It appears to be this:

I am looking JUST for a replacement filter,  The bracket and gasket are fine.  

The part number for the filter is SP-2979, stamped on the side.  It is a K&N Filter:

...which does not appear to be made anymore.

Does anyone have any ideas where I can get a replacement filter for this?

Thanks!

Understand that's for the complete housing, gasket and filter.  The OP is trying to find a replacement filter only.

Yeah, I spent a few minutes looking for just the filter but couldn't find it. 
I would call spruce and ask them if they sell just the filter, and if they don't sell it separately ask them to pull the kit and tell me the part # of the filter is.  If they won't do it over the phone I can do it on one of my semi-daily trips there.

Good call, I'll do that next week.   Thanks!

Any PIREPS on if these filters actually increase MP?

They do because they have less filter media, when compared to other filters and let even more air through when they aren’t serviced properly.
